2021 NSPS Student Competition

INTRODUCTION

The 2021 NSPS Student Competition will be held in conjunction with the Spring meetings of the National Society of Professional Surveyors. This year’s competition will not include field exercises in order to accommodate official health and safety advice.

The Competition will begin with an online briefing event on February 16, 2021 with a presentation by NSPS of the purpose of the Annual Student Competition and purpose of this year’s challenge.

The event will not involve person-to-person contact. Therefore, potentially opening the event to teams that may have found raising funds for travel a hinderance to participation.

There will be two separate divisions, one for students matriculated into Associates degree programs and one for students matriculated into Baccalaureate degree programs. The status of a student’s eligibility will be their status on January 1, 2021. Any team made up of students matriculated into both Associates and Baccalaureate degree programs must compete in the Baccalaureate degree division. Graduate students may not be part of a team.

REGISTRATION

The team must email the registration form or send it via fax to +1 (240) 439-4952, no later than February 26, 2021.  There will be no fee to participate. Teams will provide a final registration form along with their Technical Report. Please direct any questions VIA EMAIL to the 2021 Competition Chairman and a CC copy with return receipt requested. Sending to both addresses will help assure aren’t any missed communications.

2021 Student Challenge

The topic for the 2020 competition was cutting edge: “The Terrestrial Reference Frames and the Geopotential Datum of 2022 of the National Spatial Reference System by the National Geodetic Survey.

The topic for the 2021 competition will be to revisit some fundamentals that underpin much of what we recognize as surveying today, along with a practical exercise in professional communication, such as you may be called onto produce in your future professional practice.

The challenge for Associate degree teams will be different from the challenge for Baccalaureate degree teams as follows

Fundamentals Challenge for Associate Degree Teams

Greek philosopher Pythagoras first suggested that the Earth was round in 500 BC Later, Greek philosopher Aristotle proved Pythagoras correct. Eratosthenes of Cyrene, a Greek polymath, poet, astronomer, mathematician, librarian, and geographer, established the Earth’s circumference in 235 BC.

Your mission, should you decide to take it, is to study their methods and submit a report. You must find a way to imitate Eratosthenes’ using a technique of your design inspired by him and derive a circumference of the earth from your findings using tools and resources available in your area. Use of artificial satellite technology is disallowed.

The report should take the form of a proposal as if proposing the plan to a state agency or patron. Please include in your report your analysis of the ancients’ work, how you planned to imitate Eratosthenes techniques, describe the progress of your survey, and present the results. Using a style similar to a formal research paper is the idea. Convince the reader you have the ability, within your area to complete the survey and present plausible results within a realistic budget. Approach the problem like a project manager.

Chairman’s comment: The report should reflect how you would propose to accomplish the project, not an idealized scenario.  Assume the reader is an agency or client who will be persuaded by a realistic assessment of your situation (your state, your school, funds, &c.). An appendix that contains the means by which you derived the content of your report will aid judges in their assessment.

Extra: Not required, but may help break a tie. Show how Pythagoras could prove the theorem named for him without using equations. Then show how Eratosthenes could calculate the circumference of the earth in a similar way.

Advanced Challenge for Baccalaureate Degree Teams

The 18th century saw natural philosophers debate how the earth’s shape varied from that of a sphere. People of renown such as Cassini and Newton disagreed whether the shape was oblate or prolate. With time, sufficient surveys were performed to answer the question.

Your mission, should you decide to take it, is to perform the Fundamental Challenge above, followed by making a similar study and proposing a realistic project of observations to determine evidence of Earth as an ellipsoid using the tools and resources available to you in your area. You must find a way to imitate what was accomplished in the 18th century expeditions using a technique of your design and derive an ellipsoid parameter of the earth from your findings. Use of artificial satellite technology is disallowed.

The report should take the form of a proposal as if proposing the plan to a state agency or patron. Please include in your report your analysis of the ancients’ work, how you planned to imitate Eratosthenes techniques, describe the progress of your survey, and present the results. Using a style similar to a formal research paper is the idea. Convince the reader you have the ability, within your area to complete the survey and present plausible results within a realistic budget. Approach the problem like a project manager.

An appendix that contains the means by which you derived the content of your report will aid judges in their assessment.

REPORT (PROPOSAL) SPECIFICATIONS

Teams will provide one hard copy of their Report as well as one digital copy, as a single PDF. The hard copy should be bound and shipped to the NSPS office along with the digital copy on a flashdrive.

National Society of Professional Surveyors
Attn: Trish Milburn
5119 Pegasus Court, Suite Q
Frederick, MD 21704

The Report should not exceed 100 pp. double spaced. The Report shall be the original work of the team, with all quotations, properly cited and sourced in accordance with applicable standards of academic honesty and professional conduct. Appendixes of cited, non-original material, not to exceed an additional 50pp. can be included but is not mandatory. The Appendixes should not be “filler” but be thoughtfully chosen and referenced in the Report.

The writing standards for the Technical Report shall be those for manuscript submission to the Surveying and Land Information Science Journal. The Paper copy of the Report submitted shall be double spaced, printed on one sided, 12 pt. Times New Roman Font, 1” margins all around. The PDF must be named as follows: yourschoolabbreviation_Report_NSPS_2021.PDF. There should be a Table of Contents and a Title Page.

The Report may receive additional bonus points if at the time the Technical Report is submitted a marked-up DRAFT copy is also supplied which clearly documents that the paper was critiqued by the team’s institution’s “writing center”. If no writing center exists, the review may be conducted by a faculty member outside the contestants’ academic department.

The PDF should also include as the FIRST PAGE (prior to the actual Report), the final registration form. Binders must be received at the office of NSPS no later than 5:00 pm April 2, 2021.

National Society of Professional Surveyors
Attn: Trish Milburn
5119 Pegasus Court, Suite Q
Frederick, MD 21704
204-439-4615, ext. 105

There will be no exceptions to April 2 deadline. It is the responsibility of the team to verify receipt of their submission by NSPS. Students should use such methods as certified mail, return receipt requested or carrier tracking numbers, and then the team should follow up with a phone call to NSPS HQ once delivery is confirmed by the carrier to double check.

OTHER PRESENTATIONS

At present there is under consideration an opportunity for presentation of reports or some form for team quiz-bowl. Registrants will be notified as plans become develop.

AWARDS

Awards will be given to the 1st, 2nd, and 3rd place teams in each category including monetary awards.  Each advisor and participant will receive a special token for participating.

How to Start a Design Level Drone Mapping Business

I get asked a lot what I recommend for a startup drone mapping business. Before answering the question we must consider the intent of the operation. After all, there are two types of drone mapping: generic 3D mapping and its much more intricate cousin, design level survey mapping.

3D mapping is done at various levels of accuracy and flying heights mostly with manned aircraft ranging from 1′ to 15′ contour levels. This type of mapping is generally not used by design engineers to create accurate man-made features. It is used for dirt quantities, layout and design of roads, highways, power lines, etc.

The lowest that manned aircraft can fly is at 1000′ AGL which equates to 2.5cm level mapping which is design level mapping but very expensive to acquire.

Design level survey mapping is also 3D mapping however the accuracy is within 0.07′ (2 cm) or better. Engineers and Architects can use this mapping to design man-made features such as buildings, parking lots, streets and so on that require a higher level of accuracy.

Drones can easily capture imagery for design level survey mapping if done right. One button solutions using automated flight software can achieve 3D mapping at various levels of accuracies depending upon the drone camera/sensor and software being used for processing.

Design level survey mapping is the next level which takes more than a one button solution.

Design level drone mapping - our work is our pleasure!
Design level survey mapping – our work is our pleasure!

More Than a One Button Solution

Having surveying knowledge is the key to getting professional design level survey mapping. You need to understand surveying datums such as State Plane Coordinate System, UTM Coordinate System, Ground vs Grid, Grid Adjustment Factors, Geographic Coordinate System, design constraints, grade breaks, planimetrics, contour generation and breaklines to mention a few.

Being a licensed Professional Land Surveyor is a huge benefit. Teaming up with a licensed professional will fill that gap as well.

A UAV (drone) is just a tool and in a surveyors hand is priceless when it comes to design level survey mapping.

Tradition surveying knowledge takes drone mapping to the next level
Taking drone mapping to the next level

Surveying Knowledge is Priceless

You need a drone with a camera/sensor that will meet sufficient accuracy requirements.

  • I use a DJI Mavic 2 Pro and Inspire 2 with a x5s camera/15mm lens.
  • I use the right number of GCPs set in strategic locations using a survey grade GPS to get a solid aerial triangulation solution.
  • I use Metashape Pro to process the imagery and measure the ASPRS RMSE values. Breaklines are created along grade breaks, man-made features and extracted as a DXF file. A rectified orthomosaic is also created.
  • The DXF is imported into Civil 3D to create a 3D surface. Planimetrics are added to create a design level survey map for engineers and architects to use for their design.

How to start a drone mapping business

I use both an iMac and Windows computer to process all of the data. So how to start a drone mapping business? In conclusion, here is my survey mapping equipment list:

  • Survey knowledge (priceless)
  • Survey grade GPS equipment ($20k+)
  • Mavic 2 Pro ($2k) or Inspire 2 with x5s camera & 15mm lens ($8k+)
  • Mini iPad with Litchi ($400+)
  • Metashape Pro for breaklines and orthomosaic ($3500)
  • Civil 3D to build a surface. ($2400 per year)
  • Computer ($3000+)

Total = $37,300+ to get started

This does not include training, office, vehicle, insurance and all of the other factors it takes to run a business.

As you can see it is not cheap to get into design level survey mapping. It has taken me years to build everything I have to provide this type of service. Working with a company such as Cooper Aerial provides the necessary tools and clients to bring it all together.

You don’t have to have 46+ years experience in surveying but you do need to work with someone that does have surveying experience. Most states in the US require that design level survey mapping be done by or under the direction of a licensed professional land surveyor.

Anyone can fly a drone. Not everyone can deliver design level survey mapping.
